Alex H. Ardila, Van Duong Dinh, Luigi Forcella

摘要:

本文研究了非线性光学中一类具有立方相互作用的非线性薛定谔方程解的渐近动力学。我们提供了尖锐的阈值标准,导致全球适定性和散射的解决方案,以及在有限时间内(各向异性)对称的初始数据的奇点的形成。利用Morawetz估计和相互作用Morawetz估计证明了自由渐近结果。通过变分分析和一个常微分方程的论证,克服了基于维里型恒等式的凸性论证的不适用性。

英文摘要:

We study the asymptotic dynamics for solutions to a system of nonlinear Schrödinger equations with cubic interactions, arising in nonlinear optics. We provide sharp threshold criteria leading to global well-posedness and scattering of solutions, as well as formation of singularities in finite time for (anisotropic) symmetric initial data. The free asymptotic results are proved by means of Morawetz and interaction Morawetz estimates. The blow-up results are shown by combining variational analysis and an ODE argument, which overcomes the unavailability of the convexity argument based on virial-type identities.
